To (if/ZZ whomc't may concern Be it known that 1 CHARLES BEAD, a citi- `zeii of the United `States, and resident of Morris ParkQborough of Brooklyn, county of Kings, city and State of New Y Ork, have invented certain new and useful Improvements in Snap Fasteners.

This inventionrelates to in'iprovements in snap fasteners and the principal object of the invention resides in the provision of a i wire or stamped from a Halt sheet ot 1`1aterial. f

` Still another object of the invention reL sides in the provision of a snap fastener `Which may, with slight modification of construction, be utili/.ed as a glove fastener,

garment fastener', or asa means for securing side curtains in place on a motorv vehicle.`

A furtl'ier and'inore specific object of the invention, resides in the infovision of a fas? tener which, when used as a garment fastener, may, by slight change inthe-'construe tion of the spring, avoid the necessity of piercing the fastener' shell to receive the securing means by which thev device is attached to the garment. y i l/Vitli these andl other objet-.ts in `vieny the invention consists vof a novel construction, combination and arrangemeilt of parts which iv ill be fully set forth. in the. following specification,claimed and illus f 'ed in the acconipanying drawings, in lWhich ,Y

This body 11` is provided with a central opening 13 to receive the stud inem ber Whichwvill be more fully hereinafter describe-d. cover plate 14 formed withv a tubular extension 15 fits" Within the flange 1&2L and is held in place by means of* an in-A turned flange" 1.6 at) the' edge ofthe flange 12, as Will be` clearly' seen" upon reference to The socket meniber thus described is provided with a. clamping spring 1T which consists of a bight portion larraiiged on the inner face of the shell or socket member in .sm-h a. manner that itf intersects theedge of the opening 13; Formed atthe opposite' ends of the bight portionltarethe yielding claniling arms' 19 which, likel the bight portionl 18 intersect.` the edge' of the opening 13.` These arms are formed atY the endsoppositcthose connected" to the` bight portion withbent back portions" 20 which in" turn are i formed integrally With the resilient arched members `21 formed on the retaining portion 22 of thespring which liesV agaiiist the inner side of the flangelQ. y

The stud member used` in connection i with the socketI men'lber above describedA vis 'desig nate'd by the numeral 23 and comprises`v a ba se plate having extending centrally there-` froinalta'pered neck 24' formed at the extreme upper end with a head 25, which is of a diameter to slip through the opening 13 and the neck 24 is reduced so that the bight portion 18 and the arms 19 of the spring 17 normally lie in planes tangential with the periphery of the neck. l j

Upon reference to Figs. S and 9, it will be seen that the same type of spring is utilized but that the shell 26 differs from the shell 10 in that it is provided with the attaching points 27 which are driven into the bow 28 so that the outer face of the shell lies flush with the outer face of the bow. In this type of device, the backing plate 29 is held against the rotary movement with relation to the shell by means of suitable ears 30 which project into recesses formed in the annular flange of the shell as illustrated in Fig. 9. A further slight difference in the structure resides in the formation of the central opening` 31 which is slightly egg-shaped, so that the bight portion 18 of the spring lies'wholly within the opening. Obviously the stud which ente-rs this opening is shaped to conform therewith and it has been found through experiment that such formation prevents relative rotary movement of the stud with the socket. i .In the type of device used as a garment fastener the spring is formed with a plurality ofv attaching` loops which extend radially vtherefrom to form eyes through which the securing threads pass. Thel socket of the garment fastener is designated Iin its entirety by the numeral 32 and comprises a pair of telescopic cup-shaped members 33 and 34 which are formed with central openings 35 and are provided at their edges with notches or mating slots 36 for the accommodation of the loops of the spring. The spring used in connection with this device consists of a bight portion 37 formed at opposite ends with the clamping jaws 3S and the bight portion and clamping jaws intersect the edge of the openings 35 so that the portions of said bight portion and jaws lie within the confinement of the openings. The jaws are formed at their ends opposite those formed on the bight portion withextensions 39 terminating at their outer ends in loops 40 which extend radially from the socket. As shown in Figs. 3 and 4, the slots 41 through which the extensions 39 project are enlarged to provide holes to permit the jaws to be readily sprung outwardly and avoid binding at this point. vThe loops 40 are formed with arcuate portions 42 which lie within the flanges of the socket members and similar loops 43 are formed on the arcuate members 42 and extend radially from the socket.

The stud used in connection with the garment fastener structure is best illustrated in Figs. 6 and 7 and comprises a base plate 44 formed at its periphery with a bead 45 in which the arcuate portions 46 of a suitable reinforcing wire lie. This bead is cut awa v at spaced intervals around the periphery of the base plate and extending through the cut away portions are the radial loops 47 formed of the reinforcing` wire 46.

The operation of the fastener is as follows :Upon the withdrawal of the stud head from the socket, pressure is applied at the upper side or that across which the bight portion of the spring` extends. Obviously this portion of the springmay be stationary and the pressure will cause the arms to spring` upwardly so that a slight downward movement of the stud head will free the same, and thus permit it to be readily withdrawn. Due to the resilience of the members 21, it will be seen that the spring may be easily manipulated and the head may again be inserted with relative ease. The same is true of the structure illustrated in Fig. 3 as the resilience transmit through the. extensions 39 and the loops 40 so that the resiliency is distributed over a relatively large area, and the device will at all times return to its original position. Obviously, in lieu of the wire type of spring, a flat stamped spring may be utilized and the head when in the socket, will be firmly engaged on three sides so that danger of its accidental re moval is eliminated.

In the modified form of the device illustrated in Figure 10, the stud mnnber 48 is secured to the bow or other rigid support 49 and an elongated socket member is secured to the inner curtain 51 and received the stud member as clearly shown. The outer curtain 52 carries a stud member 53 which projects into the socket member 50 so that when the device is in place the two curtaiiis will be secured in parallel relation.

In the modification shown in Figure 11 the structure is essentially the same as that illustrated in Figures l and 2 with the exception that the ends of the resilient arms I9 opposite those connected to the portion ls are provided with` return jbends forming the parallel extending portions :'i-l` the ends of which are curved to conform lo the curvature of the socket member as at 55. (lbviously such formation will increase the area over which the resiliency of the arms vI9 distributed, thereby increasing the resiliencv of the whole. .y

While in the foregoing there has been shown and described a preferred en'lbodiment of this invention, it is to be understood that certain minor changes in the details in the construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

That is claimed is 1. A snap fastener comprising a base hav` ing an egg shaped perforation therein. a. continuous ring shaped spring having a substantially triangular closed loop, the straight portions of said loop overlying a` portion of the perforationand a headed stud adapted to be entered into the perforation, said stud `2. A snap'fastener comprising a headed stud, a base, formed to comprise an eggshaped opening therein, a spring having a ring shaped portion and a suhstantiallyitriangular shaped Closed loop portionfwithin said ring, the straightportions of said loop overlying a portionof the perforation, and

`being adapted to engage the stud when the aame is inserted in the perforation.

3. A snap fastener comprising a stud,`a perforated base adapted to receive the stud, a spring having a ring shaped portion engaging the Wall of said hase and a substantially closed triangular loop, the straight portions of said loop overlying a portion of the perforation whereby, when the stud is inserted into the perforation, the spring will engage the saine and a perforated oover for the base. v
